I got a 2 mth old Nikon D300S, 18-200mm VR2 lens and SB900. Recently when i took some pics, i enlarge to 100%, the pic is not sharp at all, my friend said might be some backfocusing problem, anyone know how to check and fix this problem?

it might be camera shake. Try using tripod and see whether the pic is better or not...:cool:
 

Quick way to check is to place 2 AA batts on the table, one slightly behind (diagonally) the other. Then with your cam at the lowest f# focus on the nearer battery. If the back battery is sharper, then the probably has a problem.

Not a very sceintific check. LOL
 

Place a series a battery or something as guide. Then focus on the middle on. Look which is sharper on your computer. If the middle one that was focus is the sharpest. Probably it is not back focusing problem, it is just that 18-200 is not a super sharper lens and you are using a big screen. LOL

Why not do yourself a favor and post a picture here that you think is not sharp. Do include your shot settings too, shutter, aperture, ISO and a 100% crop.
 

one from each folder?

Let me rephrase.

Select a couple of pics yourself, where you think the apparent problem is most pronounced.

Then post the links to the images here, complete with EXIF data. And tell us where your focus point is for each picture.

Without these info, especially on where your focus point was, there is no way in hell we can tell you if there is any back or front focusing problem.

Hard to advise you if you dont't tell us which one to look. Some pic might becamera shake and some might be DOF,etc... pls be more specific.:dunno:
 

one from each folder?

Even in each folder one can easily find images with handshake, OOF and other possible reasons for not being sharp. There is more than one simple reason why the image is not sharp - some can be attributed to you, some can be caused by conditions and some can be caused by the way the camera works. Please be specific, otherwise a detailed analysis and advice is not possible.
 

From all the pictures I see.. I cant figure out which one you referring too aboutnot being sharp. Some of it are reasonably sharp for a 18-200 VR Nikkor. Actually from my opinion, that is a standard quality sharpness you can get from a 18-200 VR. Your daytime outdoor picture looks reasonably sharp to me. Those taken on long exposures at night can be due to handshake, tripod not steady and wind blowing and caused the blurness and lastly, you did not turn off the VR.

I think you lens or body is Ok.
 

So no news from the TS?

Maybe you should hold off offering wedding photography services before you solve this issue. You might end up screwing up someone's big day.
 

So near Christmas, TS must be busy covering events.
